Description

Technical Field

[0001] The present invention relates to the technical field of toilet deodorization, in particular to a toilet deodorization structure and a deodorization control method. Background Art

[0002] In the prior art, the odorous gas around the toilet is guided into the water curtain assembly through the air inlet assembly for purification. The air filtered by the water curtain assembly then flows to the air outlet assembly area, which is integrated with a sterilization device to ensure that the air is sterilized and deodorized before being released back into the toilet environment, thereby achieving the deodorization effect of the toilet. The prior art has the following problems: (1) There may be a risk of secondary pollution: If the filter device is used for a long time and is not maintained and cleaned in time, bacteria, mold and other microorganisms may breed inside it, causing secondary pollution, or if the sterilization device fails, the polluted air will be discharged back into the room, losing the sterilization effect. (2) Increased parts cost and maintenance cost: If an internal circulation air duct is used, a filter module must be added, and a sterilization module may also be added, which will increase the product cost and lead to an increase in the price at the customer end; at the same time, it may need to be replaced regularly, or if it breaks, it needs to be repaired, which will increase additional maintenance costs. Summary of the Invention

[0003] The present invention aims to solve at least one of the above-mentioned technical problems in the related art to a certain extent. To this end, the present invention provides a toilet deodorizing structure.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] The present invention also proposes a deodorization control method based on the toilet deodorization structure.

[0006] According to the first aspect of the present invention, the toilet deodorization structure includes a toilet, a bathroom heater, a deodorization pipe and an air valve assembly. The deodorization pipe is arranged outside the toilet, and a first air duct is arranged inside the toilet. One end of the first air duct is connected to the toilet cavity of the toilet, and the other end is connected to the deodorization pipe. The bathroom heater includes an outer shell and a first exhaust fan. The bottom wall of the outer shell is provided with a first air inlet. The first exhaust fan is installed in the outer shell and is located at the first air inlet. The side wall of the outer shell is provided with a first air outlet. The air valve The component is arranged below the shell, and the air valve component includes a cover and a movable plate. The cover is arranged around the four sides of the first air inlet, and the second air inlet and the third air inlet are opened on the cover. The first air inlet, the second air inlet, the third air inlet and the first air outlet are connected. The movable plate can move to close or open the second air inlet, and the third air inlet is connected to the deodorization pipe. The ratio of the cross-sectional area S1 of the deodorization pipe to the opening area S2 of the second air inlet is S1 / S2<1 / 4.

[0007] The toilet deodorizing structure according to the embodiment of the present invention has at least the following beneficial effects:

[0008] 1. The present invention changes the deodorization of the toilet from internal circulation to external circulation by sharing the exhaust duct of the bathroom heater. The air valve assembly is used to switch the air duct. When the second air inlet is opened, the deodorization duct is long and thin, and the cross-sectional area of ​​the deodorization duct is much smaller than the opening area of ​​the second air inlet, so that the pressure loss of the deodorization duct is relatively large. The indoor wind will enter the first air inlet from the second air inlet, and then be discharged to the outside through the first air outlet. At this time, it is the same as the ventilation mode of an ordinary bathroom heater, and is suitable for bathing and dehumidification scenarios. When the second air inlet is closed, the pressure loss of the second air inlet is infinite, and the wind enters from the toilet end, flows through the deodorization duct through the third air inlet and the first air inlet, and then is discharged to the outside through the first air outlet, thereby achieving toilet deodorization. It is suitable for toilet scenes with strong odor. In addition, the movement stroke of the movable plate can be controlled to control the opening area of ​​the second air inlet, so that the pressure loss of the second air inlet and the deodorization pipe is basically the same, allowing air to enter both the second air inlet and the third air inlet, which can achieve ventilation in the bathroom and deodorization of the toilet.

[0009] 2. The present invention guides the odor of the toilet directly and effectively into the external deodorization pipe, and then discharges it to the outside. This process cleverly bypasses the dependence on the filtration module and the sterilization module, fundamentally eliminating the risk of secondary pollution from the source, and ensuring the purity and hygiene of the environment; it can also save the cost of parts for the filtration module and the sterilization module, which benefits the customers; at the same time, it also does not require customers to perform regular maintenance, reducing the customers' maintenance costs.

DETAILED DESCRIPTION

[0035] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0036] Reference Figure 1-7A toilet deodorization structure includes a toilet 100, a bathroom heater 200, a deodorization pipe 300 and a damper assembly. The deodorization pipe 300 is arranged outside the toilet 100. A first air duct 110 is arranged inside the toilet 100. One end of the first air duct 110 is connected to the toilet cavity 120 of the toilet 100, and the other end is connected to the deodorization pipe 300. The bathroom heater 200 includes a shell 210 and a first exhaust fan 220. The bottom wall of the shell 210 is provided with a first air inlet 211. The first exhaust fan 220 is installed in the shell 210 and is located at the first air inlet 211. The side wall of the shell 210 is provided with a first air outlet 212. The damper assembly Located below the outer shell 210, the air valve assembly includes a cover 410 and a movable plate 420. The cover 410 is arranged around the first air inlet 211. The cover 410 is provided with a second air inlet 411 and a third air inlet 412. The first air inlet 211, the second air inlet 411, the third air inlet 412 and the first air outlet 212 are connected. The movable plate 420 can move to close or open the second air inlet 411. The third air inlet 412 is connected to the deodorization pipe 300. The ratio S1 / S2 of the cross-sectional area S1 of the deodorization pipe 300 to the opening area S2 of the second air inlet 411 is less than 1 / 4. In this embodiment, the first air duct 110 is arranged inside the movement of the smart toilet 100. The front end of the first air duct 110 is connected to the toilet cavity 120 of the toilet 100, and the rear end extends out of the toilet 100 and is connected to the deodorization pipe 300. The deodorization pipe 300 can be buried in the wall. The diameter of the deodorization pipe 300 is about 40-50mm. The bathroom heater 200 is installed on the ceiling 500 of the bathroom. The deodorization pipe 300 extends upward to the ceiling 500 and is connected to the third air inlet 412. The diameter of the exhaust pipe 230 of the bathroom heater 200 connected to the first air outlet 212 is about 100mm.

[0037] Working principle: By sharing the exhaust duct of the bathroom heater 200, the internal circulation deodorization of the toilet 100 is changed to external circulation deodorization, and the air valve assembly is used to switch the air duct. When the second air inlet 411 is opened, since the deodorization pipe 300 is long and thin, the cross-sectional area of ​​the deodorization pipe 300 is much smaller than the opening area of ​​the second air inlet 411, so that the pressure loss of the deodorization pipe 300 is relatively large, and the indoor wind will enter the first air inlet 211 from the second air inlet 411, and then be discharged to the outside through the first air outlet 212. At this time, it is the same as the ventilation mode of the ordinary bathroom heater 200, which is suitable for bathing and dehumidification scenarios. When the second air inlet 411 is closed, the pressure loss of the second air inlet 411 is infinite, and the wind enters from the toilet 100 end, flows through the deodorization pipe 300 through the third air inlet 412 and the first air inlet 211, and then is discharged to the outside through the first air outlet 212, thereby achieving deodorization of the toilet 100, which is suitable for toilet scenes with strong odor. In addition, the movement stroke of the movable plate 420 can be controlled to control the opening area of ​​the second air inlet 411, so that the pressure loss of the second air inlet 411 and the deodorization pipe 300 are basically consistent, allowing air to enter the second air inlet 411 and the third air inlet 412, which can achieve ventilation in the bathroom and deodorization of the toilet 100.

[0038] In some embodiments of the present invention, the second air inlet 411 is located directly below the first air inlet 211, the third air inlet 412 is provided on the side wall of the cover 410, and a second air duct 213 is provided in the housing 210. One end of the second air duct 213 passes downward through the bottom wall of the housing 210 and is connected to the third air inlet 412, while the other end passes through the side wall of the housing 210 and is connected to the deodorizing duct 300. Since the housing 210 of the bathroom heater 200 is mounted above the ceiling 500, the deodorizing duct 300 is connected to the side wall of the housing 210 and then communicated with the third air inlet 412 via the second air duct 213, so that the deodorizing duct 300 can be hidden on the ceiling 500.

[0039] In some embodiments of the present invention, Figure 7 As shown, a first air guide panel 214 is provided within the housing 210. The first air guide panel 214 forms a first air guide cavity 215. The first exhaust fan 220 and the first air outlet 212 are located within the first air guide cavity 215. The first air guide cavity 215 is used to guide air entering from the first air inlet 211 to flow toward the first air outlet 212, thereby preventing air from flowing randomly within the housing 210.

[0040] In some embodiments of the present invention, the cover 410 and the bottom wall of the housing 210 define a housing space. The damper assembly further includes a gear 430, a motor 440, and two guide rails 450. The movable plate 420, the gear 430, the motor 440, and the guide rails 450 are all mounted within the housing space. The two guide rails 450 are disposed on either side of the cover 410 and extend along the length of the cover 410. The movable plate 420 is slidably connected to the two guide rails 450 on either side. A rack 421 is disposed on the lower surface of the movable plate 420, the rack 421 being parallel to the guide rails 450. The gear 430 meshes with the rack 421, and the motor 440 is configured to drive the gear 430 to rotate. The rotation of the gear 430 causes the movable plate 420 to slide along the guide rails 450 through the meshing of the gear 430 and the rack 421, thereby opening and closing the second air inlet 411.

[0041] In some embodiments of the present invention, grooves 413 are provided on both sides of the inner top surface of the cover 410, extending along the length of the cover 410. Raised strips 422 are provided on both sides of the upper surface of the movable plate 420, which are slidably embedded in the grooves 413. The provision of the grooves 413 and the raised strips 422 can improve the stability of the movable plate 420 and reduce shaking.

[0042] In some embodiments of the present invention, the bathroom heater 200 further includes a second exhaust fan 240 and a heating module 250. The bottom wall of the housing 210 is provided with a second air outlet 216 and a fourth air inlet 217, and the second air outlet 216 and the fourth air inlet 217 are located outside the space surrounded by the cover 410. The second exhaust fan 240 is installed in the housing 210 and is located at the fourth air inlet 217. The heating module 250 is installed in the housing 210 and is located at the second air outlet 216. A second air guide plate 218 is provided in the housing 210, and the second air guide plate 218 encloses a second air guide cavity 219. The second exhaust fan 240 and the second air outlet 216 are located in the second air guide cavity 219. The second air guide cavity 219 is used to guide air from the fourth air inlet 217 to the second air outlet 216, thereby preventing airflow from running around in the housing 210. The heating module 250 is PCT heated, and a grille is installed on the second air inlet 411. The present invention links the heating function and the deodorizing function of the bathroom heater 200, which can improve the bathroom environment more efficiently and enhance the user experience from multiple angles.

[0043] A deodorization control method based on the above-mentioned toilet deodorization structure, the toilet deodorization structure also includes a temperature sensor, an odor sensor and a seat sensor, and the seat sensor is arranged in the seat ring of the toilet 100;

[0044] Deodorization control methods include:

[0045] When the seat sensor detects that the user sits on the toilet 100, the odor sensor and the temperature sensor are triggered to work;

[0046] When the odor concentration reaches a preset value and the temperature is below a first temperature, both toilet mode and heating mode are simultaneously executed. Toilet mode involves closing the second air inlet 411 and activating the first exhaust fan 220, while heating mode involves activating the heating module 250 and the second exhaust fan 240. Furthermore, the heating mode is deactivated when the seat sensor detects that the user has left the seat. After the user sits down and detects a low temperature, the heating mode is activated simultaneously with deodorization to raise the ambient temperature and improve toilet comfort. For example, heating mode is activated when the temperature is set below 18°C. When both toilet mode and heating mode are executed simultaneously, odors from the toilet 100 flow through the third air inlet 412, the first air inlet 211, and the first air outlet 212 and are discharged outdoors. Indoor air flows through the fourth air inlet 217 and the second air outlet 216, where it is heated and blown out as hot air, forming an internal circulation system. Two independent air guide chambers are provided within the housing 210, ensuring that the airflows from the two modes do not interfere with each other and do not mix.

[0047] In some embodiments of the present invention, a temperature sensor and / or an odor sensor is provided in the toilet 100. The odor sensor can be provided on the front side of the movement, facing the toilet cavity 120 of the toilet 100, and can provide timely feedback on the odor information of the toilet 100.

[0048] In some embodiments of the present invention, when the odor concentration reaches a preset value and the temperature is higher than a first temperature value and lower than a second temperature value, the toilet mode is activated. When the temperature is moderate, only the toilet mode is activated, for example, when the temperature is set between 18°C ​​and 26°C, only the toilet mode is activated.

[0049] In some embodiments of the present invention, the toilet deodorization structure further includes a humidity sensor. When the odor concentration reaches a preset odor value and the temperature is higher than a first temperature value and lower than a second temperature value, if the humidity is greater than the preset humidity value, the standard ventilation mode is first executed. After the humidity is lower than the preset humidity value, the toilet mode is switched to. The standard ventilation mode opens the second air inlet 411 and activates the first exhaust fan 220. When the temperature is moderate and the humidity is high, the standard ventilation mode is first activated to dehumidify the toilet, and after the humidity is reduced, the toilet mode is activated. For example, the standard ventilation mode is activated when the humidity is set to greater than 80%.

[0050] In some embodiments of the present invention, when it is detected that the odor concentration reaches a preset odor value and the temperature is higher than a second temperature value, the toilet mode and the blowing mode are executed at the same time, and the blowing mode is to start the second exhaust fan 240. Furthermore, the blowing mode is turned off after the seat sensor detects that the user has left the seat. The blowing mode does not start the heating module 250 and only blows out normal temperature air. When the indoor temperature is high, the blowing mode is turned on while deodorizing. When the fan is used, the comfort of going to the toilet is improved. For example, the blowing mode is turned on when the temperature is set to be higher than 26°C.

[0051] In some embodiments of the present invention, the toilet deodorization structure further includes a humidity sensor. When the odor concentration reaches a preset odor value and the temperature is higher than a second temperature value, if the humidity is detected to be greater than the preset humidity value, the standard ventilation mode is first executed. After the humidity is less than the preset humidity value, the system switches to the toilet mode and the blowing mode. The standard ventilation mode opens the second air inlet 411 and starts the first exhaust fan 220. In indoor environments with high temperature and high humidity, the standard ventilation mode is first activated. After the humidity decreases, the toilet mode and the blowing mode are activated. The blowing mode acts like a fan to improve toilet comfort.

[0052] In some embodiments of the present invention, after the seat sensor detects that the user has left the seat, the toilet mode continues to operate for a set time and then turns off. For example, after the user leaves the seat, the toilet mode continues to operate for 10 minutes and then turns off, thereby removing any remaining odors and keeping the indoor air fresh.

[0053] In some embodiments of the present invention, the odor sensor performs a timed detection when the user is not seated, performing a detection at set intervals. When the detected odor concentration reaches a preset value, the standard ventilation mode is activated, which opens the second air inlet 411 and activates the first exhaust fan 220. If an odor is detected while the user is not seated, the standard ventilation mode is activated to deodorize the indoor air and facilitate subsequent use. For example, if the detection is set to occur every half hour, the standard ventilation mode is activated for 15 minutes if an odor is detected.

[0054] It should be noted that the deodorization control method described in the present invention is only for modes related to deodorization, and other modes not related to deodorization are not described. In addition to the modes mentioned in the present invention, the bathroom heater can retain the original mode, such as starting the internal circulation heating mode and the dehumidification and ventilation mode separately. The deodorization control method added by the present invention will not affect the original function of the bathroom heater.

[0055] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
